P. 171
Why: Math talks build uency by encouraging students to think about the numbers, shapes, or algebraic expressions and rely on what they know about structure, patterns, and properties of operations to mentally solve a problem. While participating in these activities, students need to be precise in their word choice and use of language (MP6).
Launch
Display one problem at a time. Give students quiet think time for each problem and ask them to give a signal when they have an answer and a strategy. Keep all problems displayed throughout the talk. Follow with a whole-class discussion.

Activity Synthesis
Ask students to share their strategies for each problem. Record and display their responses for all to see. To involve more students in the conversation, consider asking:
• “Who can restate [student]’s reasoning in a di erent way?”
• “Did anyone have the same strategy but would explain it di erently?” • “Did anyone solve the problem in a di erent way?”
• “Does anyone want to add on to [student]’s strategy?”
• “Do you agree or disagree? Why?”
